I think it's important to mention with the DateTime class that if you're trying to create a system that should store UNIX timestamps in UTC/GMT, and then convert them to a desired custom time-zone when they need to be displayed, using the following code is a good idea:

<?phpdate_default_timezone_set('UTC');?>

Even if you use something like:

<?php$date->setTimezone( new DateTimeZone('UTC') );?>

... before you store the value, it doesn't seem to work because PHP is already trying to convert it to the default timezone.
